Corey Lewandowski, who was campaign manger for Donald Trump in 2016 until being fired for being charged with battery after he grabbed a female reporter, joined Donald Trump on stage in Michigan Saturday night.

Lewandowski briefly took the microphone, and confusedly introduced Trump as “the next president of the United States.”

But not before he appeared to flash the “OK” symbol, as captured by Fox News cameras which had a wide-view shot at the time.

The “OK” symbol is widely used by white supremacists like Richard Spencer, though alt-right types like Stephen Miller and random interns also use it.
